Thank you for any help you can offer! I have a 2000 Nissan Altima that works great except when the weather becomes cold in the winter. The brakes don’t work when I turn on my car. The brake lever will not press down at all and once or twice (before I realized this was happening) my car went sliding down the road without an ability to stop. I can’t tell if they start working after the car warms up or after I’ve pumped them for a while because they’ll start working again at random times. Sometimes it takes a few seconds and sometimes it takes a few minutes. Thank you for any advice! Have a wonderful day!
